Someone is hacking the emergency broadcast system. This was only a test. If they can use that to trigger a hub they will alert an entire region, or even the nation, not just one station.

This is as close to the end of hackers as real life could come.

I bet there is a room full of people at the dhs that need new underwear.

I wasn't sure where I got the link - thanks. I saw the clip earlier elsewhere but your article has actual research/information that confirms it and explains where it came from, etc. Actually makes it more interesting. This is a very bizarre thing.
